DEIONIZATION SYSTEMS
The Deionization System is the process of removing minerals, namely cation and anion ions, in water. This process is done by means of ion exchangers in the process that contain resin filler. The unit where the cation ions are removed is called the Cate Exchange and the unit where the anion ions are removed is called the Anion Modifier. The unit that contains both types of resin together, that is, where both anionic and cationic ions are removed, is called Mixed Bed.
Raw water passing through ion exchangers replaces its cationic charges (Ca, Mg, Na) with H+ ion bound to cation exchanger resins and Anionic charges (Cl, SO4, HCO3, SiO2) with OH- ion bound to Anion exchange resins. As a result of ion exchange, OH- and H+ ions given to water combine among themselves to form the water molecule. At the exit of the system, the water that is purified from positively and negatively charged ions is highly purified. The resins that receive the ion charges in the water reach the saturation point after a while, that is, they begin to not produce water of the desired quality. The refreshment of the depleted resins (cleaning from the ions they retain) occurs by the regeneration process. During regeneration, anionic resin renews itself with caustic and cationic resin with acid.
